A method carries out a switchover of an on-load tap-changer using a drive system. The drive system includes at least one motor which acts on a drive shaft, a control device and an encoder system which is directly or indirectly coupled to the drive shaft. The method includes receiving a signal for switching the on-load tap-changer from the control device; determining by the control device whether switching to a current tap was performed from an upward or downward direction, and whether switching will be performed to a next tap in the upward or downward direction; selecting, on the basis of the determination, one of a plurality of travel profiles for the drive system of the on-load tap-changer, on the basis of which the switchover is carried out; and carrying out and monitoring the switchover by the drive system according to the selected travel profile.

A drive system drives a switch. The drive system includes: a drive shaft connecting the drive system to the switch; a motor configured to drive the drive shaft; a feedback system; and a controller. The feedback system is configured to: determine at least one value for a position of the drive shaft; and generate a feedback signal based on the at least one value. The controller acts on an operation of the motor depending on the feedback signal.

In a method for cleaning an on-load tap changer () in a regulating transformer (), provision is made for the on-load tap changer () to comprise a moving contact () and a fixed contact (); for a cleaning signal to be generated; for the moving contact () to be frictionally moved relative to the fixed contact () on the basis of the cleaning signal. An on-load tap changer () in a regulating transformer () comprises: &#x2014;a moving contact () and a fixed contact (); &#x2014;a contact drive () which is coupled to the moving contact (); &#x2014;a control device () which is connected to the contact drive () and is designed in such a manner that the control device can generate a cleaning signal and can transmit said signal to the contact drive (); wherein the contact drive () is designed in such a manner that the contact drive can frictionally move the moving contact () relative to the fixed contact () on the basis of the cleaning signal.
